Product Overview
Operating environment requirements for significant vertical lift are met by this eight-stage 8-inch series submersible pump. It is designed for intensive water distribution in agricultural and industrial sectors needing high-volume delivery from deep underground sources. The assembly supports vertical installations in deep wells or horizontal deployment in pressure boosting stations with an inclination. This model serves as a dedicated solution for municipal networks requiring consistent lift and flow.
Performance characteristics for this configuration include a maximum head of 204.1 m and a flow capacity of 1216 L/Min through the 125 mm discharge head. The unit is equipped with a 37 kW motor drawing 81.8 Amps of rated current from a 415v three-phase electrical supply. Efficiency is maintained through a semi-axial hydraulic configuration achieving nominal delivery rates at 2900 rpm. These parameters are verified for clean water with standard density.
The structure is fabricated from cast AISI 316 Stainless Steel for wetted hydraulic parts including the delivery casing, suction casing, and impellers. The motor is also constructed from 316 Stainless Steel and is rated for contact with liquids up to 25°C. The system handles water with suspended sand levels reaching 100 g/m³ through its eight-stage hydraulic arrangement. A duplex stainless steel shaft and coupling transmit power through the assembly during industrial operation.
This electric pump supports immersion depths of 350 meters and features an integrated non-return valve to handle backflow during system shutdown. Physical dimensions include a 198 mm maximum overall diameter, fitting within standard 8-inch borehole casings including motor cable covers. Internal clearances are maintained by EPDM 70 bearing bushes and technopolymer wear rings supporting the duplex shaft alignment. The unit is intended for continuous industrial and municipal service projects.
FEATURES
- A duplex stainless steel taperlock system secures the impellers to the shaft for torque transfer.
- Stainless steel cable covers provide mechanical protection for motor power leads along the casing.
- EPDM 70 bearing bushes support the pump shaft assembly and handle mechanical loads during rotation.
- A stainless steel suction strainer excludes large particles from entering the hydraulic stages.
- Internal technopolymer POM-C wear rings maintain hydraulic clearances and reduce internal friction.
- Mechanical connection of the 8-inch motor follows NEMA standards for industrial system compatibility.
- The integrated non-return valve features a stainless steel spring to prevent fluid backflow.
